Abstract: One of the most serious complications in oil production and transportation is the intensive deposition of as-falto-resinous and
paraffin deposits (ASPs). In this work, the effectiveness of solvents of different chemical nature for the removal of ASPs was
evaluated. Based on laboratory data, conclusions were drawn about the use of noninogenic surfactants, alcohols with different
molecular weights, and the optimal ratio of the alkane and aromatic components for the dissolution of paraffin-type ASPs.
Index terms: processing technologies, asphalt-resinous and paraffin deposits.
